Technical Information

First Stage

  • Air balanced flow-through piston in a full titanium body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
  • Patented XTIS (Extended thermal Insulating system) thermally insulates the inner mechanism from the environment, improving cold-water resistance by 30% and delaying ice formation in extreme cold water conditions without compromising breathing performance. Key insulation system components are visible in blue.
  • Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
  • Two opposing high pressure ports allow the first stage to be positioned either up or down.
  • Four high-flow and one axial super high-flow low pressure ports on a swivel turret maximize hose routing options.
  • External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.
  • Available in 3364psi/232bar INT.
  • Weight: INT 232 (oz/g): 16.8/475.
  • Airflow at 2900psi/200bar: (l/min/SCFM): >8500/301.
  • Intermediate pressure (psi/bar): 133-142/9.2-9.8.

Second Stage

  • Air balanced valve smoothes out the inhalation effort at varying depths and supply pressures.
  • Rugged reinforced technopolymer case with titanium faceplate looks good and is able to withstand years of aggressive diving.
  • Titanium barrel is rugged, anti-corrosion and lightweight for long-term reliability.
  • Diaphragm fits inside a more compact casing for maximum breathing sensitivity.
  • User controls include an easy-grip diver-adjustable inhalation effort knob and Venturi-Initiated Vacuum Assist (VIVA) lever.
  • New exhaust tee increases performance while directing bubbles out of the field of view.
  • Newly designed Compact Hi-Flow mouthpiece is mounted on an enlarged mouthpiece pipe to improve airflow as well as mouth comfort.
  • Super-flow hose features an oversized bore that allows more air to flow on each inhalation.
  • Specific matching colors (blue, pink, yellow, purple, red, white and orange) on mouthpiece and hose protector are available as an accessory.
  • Weight (without mouthpiece) (oz/g): 5.9/168.
  • Airflow at 2900psi/200bar: 1850 l/min.

SCUBAPRO's top regulator is a high performing,  ultra-light, corrosion-resistant reg system.

SCUBAPRO's top regulator technology is on display in this ultra-light, corrosion-resistant reg system. The MK25T EVO 
is machined from a solid block of titanium which will not corrode, even in concentrated saltwater conditions, promising a century of trouble-free use. It offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery 
of air on demand. The new S620 X-Ti, with its durable and good-looking titanium faceplate, embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter than the S600 but using the same-sized diaphragm, the S620 X-Ti delivers excellent performance; work of breathing has been reduced by 37% over the S600, providing effortless airflow under all dive conditions. The full titanium inlet tube is ultra-light, the large purge button improves water circulation, and the new exhaust tee increases performance while directing bubbles out of the field of view for the ultimate in lightweight performance.

 

Available: Colored mouthpieces and hose protectors that match the Seawing Nova Fins and the HYDROS PRO BC, sold separately. Colors: purple, blue, red, orange, pink, yellow, white and black.
